Total and severe injuries are reported as frequency (percent relative to total number of respondents whereas all other variables are reported as frequency (percent, relative to the number of total injuries). P-values are from chi-squared tests of differences in distributions in the control group compared to the intervention group. a do not remember/do not know were coded as missing. b Unknown and other collapsed into one category. Study conducted at three different locations in Denmark, 2010–2011
